Common Fossils of Kansas--Bryozoans

A piece of limestone on the right side of the photograph
(slightly enlarged) contains
both a fusulinid and a fragment of
the lacy type of bryozoans termed fenestellids, another
specimen of which is on the right side of the
photo. Fenestellids grew in colonies of fan-shaped fronds cemented
to an object on the bottom of the sea. (Beil Limestone, Upper Pennsylvanian)
